I recently changed my battery from my old EK to my 02 Type S, when I was changing the battery I forgot that the positive terminal was the red and black was negative. So what I did was install it backwards, black on positive, red on negative. This caused my battery fuse to blow. I replaced the 100A batter fuse... After all this my radio dosent even turn on. Dosent ask for a code or nothing, its completely off... Im assuming I blew a fuse when I was replacing the battery, what fuse or fuses could have blown? Radio was working perfectly before the battery change.

 

 

look at the fuse box cover for the one that says radio.... or get a fuse tester and start testing them all because that was a dumb move you made lol

 

Maybe you fried the stock radio.

 

Bumppppppppppp

 

Have you even attempted to troubleshoot your problems as we suggested or are you bumping your own threads to be a douche?
